max

   'max' <value> ['f'|'i'|'e'] ['l'|'u']

This keyword is used to define the upper value of the scale in the menu area (see figure 2). The number representation can be changed between int,float,exp. For example

max 1100 i

will set the upper value to 1100 and the representation to integer. A third parameter "l" (lock) or "u" (unlock) can be provided which locks the scale to certain max or min values. The selection of a different dataset will not change the scale.
